Well that depends on if there is an active battery thermal management system, like the one on the volt which can heat or cool the battery pack... Active thermal management will definitely extend the life if you live in either extreme heat or cold climates.

Phoenix weather has always been hard on car batteries. That statement could be ammended to say "EV battery packs could operate reliably for 15 to 20 years except where it really hot like Phoenix, Arizona". :^)

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
